Wireless 3x3:3 and 4x4:4

[Dolby]

What would the difference be in terms of use ?
My understanding is higher density and reliably - nothing with extra speed?

The first digit stands for the number of Tx antennas, the second for the number of Rx antennas, and the last one the number of spatial streams that can be established with clients

So if it can support 4 streams per client it could be faster as well, but client will need a 4x4:4 device as well to use all 4 streams
